Counter-Strike Gameserver Module Problem

[Tsukasa]

Hi,

I've successfully installes plesk with the gameserver key and downloaded the cs-gs module. After installing the hlds files from the steam servers, I wanted to run the gameserver. After several seconds, all I get is a yellow "!" next to the server name, which states that the server isn't available. I tried to shutdown / restart the server, but nothing seems to help. Even google doesn't know the answer, that's why I'm posting this issue here.

I hope there's some kind of fix for that.
